Our inventionl relates to scales andmore particularly to constructions designed for `.an

enameled finish. .l

In the present state of the art of scale construction it: is usual to secure associated parte to each other by the use of screws or bolts.

WV here, however, the partsV ofthe scale are given a vitreous enamel `finish the localized stresses produced by such screws or bolts frequently cause a chipping of the enamel and consequent marring of the finish. lo avoid such defect, we have designed a construction dispensing with such securing means and substituted therefor yieldable clips which may be readily engaged or disengaged without injury to the finish. These clips vary in construction according to the particular design of scale or the parts thereof which are removably secured but in each modification a resilient yieldable element is used in place of the screws or other fastening devices heretofore used. 1

Figure 11 is a section on the line lll- 11 of Fig. 5.

In the construction shown in Figures 1 and 5 to l0 inclusive, the scale is of the cylinder 0 type comprising a platform frame A, and a '.posite wall. With the type of-scalleshown pedestal including the lower reduced portion I3 and( the upper cylindrical portion C. To provide access to the cylinder the ends of the housing therefor are removable, being usually secured in position by screws ror bolts'. 55 lVith, our improved construction', however, these ends D are formed with flanges E telescopically engaging the ends of the cylinder housing C and are also provided with one or-more spring clips F for engaging a part such as the frame bar G and yieldably holding the cover in position. p K

It is also usual to provide removable painl els or cover plates on the lower pedestal por-l tion, for the purpose of gaining access to the pendulum -weight or other parts of the weighing mechanism. Such panelcover plates H we have secured by similarineans to-that used for thecylinder ends D, viz., yielfdabl'e spring. clips I which engage lugs J on theopposite 79 side of the opening in the pedestal.` To facilitate detachment ofthe panel cover II,a handle K is placedl thereon, this preferably consisting of a flat knob K having a shank K' A passing through an aperture inthe plate with 75 i a spring K2 sleeved thereon and abutting against the collar K3. This spring willl normally hold the knob close to the cover plate, but will permity of its being drawn outward when required to remove the panel. Below the panel cover plates I-I are usually smaller covers L for closing the lopening inlt-he base of the pedestal providing access to other parts of the mechanism. These plates f L, as shown, are removably secured by'a clip S5 M which is in the formI of a strip of resilient metal centrally attached to said cover L` and having ,one end M adapted to underlap. the wall of the pedestal and the oppositey end bentl to form a `yieldable flange M2. 'Thusl by lirs't" inserting the, end M intov engagement. lwith the wall `of the housing and then 'pressing the cover plate inward the flange M2 will yield to lenter into engagement yvv,itl1f...l1 OP? e5l in Figs. 2, 3 and t, glass panels'N are secured .to the fan-shaped housing Q byfglass-ho'lld# ing frames P.. These frames, instead ofhei ins-Secured. by Screws, as iS usual" erase. v1aSl1.- iond as to overlap and seat upon the housing leo' O and are provided with spring clips Q for retaining the same. As shown in Figure 3,

one of the frames P is provided with a spring tongue Q which yieldably engages a cooperating spring tongue Q2 on the member O. In Figure 4 the spring clip Q3 is secured to the frame O and engages a lug Q4 on the frame P.

Figures 5 and 6 show the scale platform R in engagement with the platform supporting frame These parts are secured to each other by providing the frame S with the radially-projecting rounded lugs T for engaging the depending channeled flange U on the Y the platform R and by then applying downward pressure upon said platform it may be snapped into engagement with the lugs T.

rThis will securely attach the platform to the frame without the 'use of bolts, screws, or other equivalent fastening means.

l'Vith allr of the various constructions above described, as well as with many other equivalent constructions, the associated parts of the 'scale are removably secured to each other by yieldably resilient clips which will not in A any Way injure the enameled finish.

What we desire to claim is:

1. In a scale, the combination with a hollow pedestal and a cylinder housing at the upper end thereof, of a removable end plate for said cylinder housing provided with a marginal flange for telescopically engaging said housing, and a spring clip for retaining said end plate upon said housing. Y

2. In a scale, the combina-tion with a holloW frame having an aperture therein and a removable cover-plate for such aperture seated upon said frame, of a disappearing knob for said cover-plate.

3.v In a scale, the combination with a hollow frame having an aperture therein and a removable cover-plate for such aperture seated upon said frame, of a knob having a shank passing through an aperture in said plate and a s rinfr sleeved unon said shank u on theV inner side of said plate normally holding said knob in close contact with the plate but permitting of its being drawn outward therefrom. g

4.-. In a-scale, the combination with a hollow frame having an outer enameled surface, the said hollow frame being provided with an aperture, of a cover plate for the said aperture, the said cover plate having its outer surface enameled and means for tdetachably securing ,the cover Plate tothe Said frame te close the said aperture, the said means being so arranged as to be entirely free from contact with the said enamel surfaces of the frame and cover plate. Y

5. In a scale, the combination with a hollow pedestal having an aperture therein, of a removable cover plate vfor the aperture seating upon the said pedestal, a frame bar within the pedestal, and means carried by the said cover plate and engageable with the said frame bar for detachably securing the cover plate to the said pedestal, the said means being housed entirely within the hollow pedestal when the cover plate is on its seat.

6. In a scale, the combination with a hollow frame having an aperture therein, of a removable'cover plate for said aperture seating upon said frame, a springclip on the inner face of the said cover late for retaining said cover plate upon said rame, and a cross member within said frame embraced by the said clip. Y

7. In a scale, the combination with a hollow pedestal having an aperture therein, of a panel cover plate for said aperture marginally seated upon said aperture, a spring clip on the inner face of and spaced from the marginal portions of the cover plate for retaining said cover plate on the pedestal, and a cross member within the said pedestal embraced by the said clip.

In testimony whereof We aiiix our signatures.
